My mother is a kind of person that likes to see everyone happy, she likes to makes everyone's wishes came true and this time it was about to fulfill one common fantasy to her two most important persons in the world for her, me, her daughter and my father. She told me she knew that me and my Dad like to have fun when she's not home, my Dad told her. He told her that we never actually had sex, we only masturbate each other what was true. But my mother knew sooner or later it would append and she decided to promote the event. The only problem is that I can't look at her face while Dad's inside me, I'm always looking the other way.
